What to know before buying

Listing details to confirm

The listing calls this size Large and gives a Small dog-breed-size classification, so the size label and intended pet fit are inconsistent. Check the entrance dimensions against your pet before choosing. The title gives overall dimensions as 50.8 x 33.8 x 11.3 cm, while the feature details give 50.80 x 33.79 x 11.30 cm. Customer opinions on fit and appearance are mixed.

Who is it for?

A good fit for

  • Cat owners and owners of small dogs comparing a plastic pet door by its stated entrance dimensions.

Less suited to

  • Buyers prioritizing a consistently secure locking bar or assured long-term flap-retaining durability, given reported customer concerns.
